With advancements, hair testing is now deemed an effective method for uncovering drug and alcohol consumption. Hair archives a prolonged history of alcohol and substances by embedding biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair offers roughly a 3-month window for detecting alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and convenient to send.
A 1.5-inch snippet containing about 200 hair strands (similar to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the perfect sample for tests and verifications. For EtG, additional elements, and/or examinations surpassing 10 panels, a specimen of 150mg is advised. It’s recommended to weigh the sample on a jeweler’s scale. In cases where scalp hair isn't available, the same amount of body hair may be taken. When head hair is mentioned, it specifically means scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key stages in the laboratory examination of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the preliminary processing of a specimen into a lab’s system. It entails checking that the specimen was sealed and shipped appropriately, allotting a random LAN (Laboratory Accessioning Number), and completing any further data entry not offered by an electronic chain of custody system.
Screening involves a rapid preliminary evaluation for drugs of abuse. While Screening is a cost-effective means to rule out drug use for most samples, a positive screen requires confirmation to be valid in court. Any samples that are presumptively positive in Screening need secondary confirmation.
If a specimen is presumptively positive in the Screening phase, additional hair is extracted from the initial specimen and prepped for Extraction. Here, drugs are extracted from hair at much reduced concentrations compared to other methods (such as urine or oral fluid), which is why hair drug screening is the most challenging method to execute.
Confirmation of any initial positive result is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed prior to confirmation as required. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair allocation and the accreditation to ISO / IEC 17025 standards.
